On incubation of bovine plasma high-molecular-weight (HMW) kininogen with purified plasma kallikrein [EC 3.4.21.8], a large glycopeptide fragment and the vasoactive peptide, bradykinin, were initially liberated; the former, named fragment 1-2, was subsequently cleaved into fragment 1 (glycopeptide) and the previously established fragment 2 (histidine-rich peptide). The isolated fragment 1-2 contained a total of 108 to 110 amino acid residues and carbohydrates, and the amino-terminal sequence Ser-Val-Gln was established. The other fragment, fragment 1, consisted of a total of 69 amino acid residues with serine and arginine (and lysine) at the amino and carboxyl termini, respectively. It contained eleven residues each of histidine and glycine, together with an oligosaccharide chain consisting of galactosamine, hexose and sialic acid. The complete amino acid sequence of fragment 1 was determined by Edman degradation and standard enzymatic and chemical techniques. These results established the following sequence: H-Ser-Val-Gln-Val-Met-Lys-Thr-Glu-Gly-Ser-Thr-Pro/Thr-Val-Ser(CHO)-Val/Leu-Pro-His-Ser-Ala-Met-Ser-Pro-Val-Gln-Asp-Glu-Glu-Arg-Asp-Ser-Gly-Lys-Glu-Gln-Gly-Pro-Thr-His-Gly-His-Gly-Trp-Asp-His-Gly-Lys-Gln-Ile-Lys-Leu-His-Gly-Leu-Gly-Leu-Gly-His-Lys-His-Lys-His-Asp-Gln-Gly-His-Gly-His-His-Lys/ArgOH.

UI	MeSH Term	Description	Entries
D007704	Kininogens	Endogenous peptides present in most body fluids. Certain enzymes convert them to active KININS which are involved in inflammation, blood clotting, complement reactions, etc. Kininogens belong to the cystatin superfamily. They are cysteine proteinase inhibitors. HIGH-MOLECULAR-WEIGHT KININOGEN; (HMWK); is split by plasma kallikrein to produce BRADYKININ. LOW-MOLECULAR-WEIGHT KININOGEN; (LMWK); is split by tissue kallikrein to produce KALLIDIN.	Cystatins, Kininogen,Kininogen,Prekinins,Prokinins,T-Kininogen,Thiostatin,Kininogen Cystatins,T Kininogen

D010446	Peptide Fragments	Partial proteins formed by partial hydrolysis of complete proteins or generated through PROTEIN ENGINEERING techniques.	Peptide Fragment,Fragment, Peptide,Fragments, Peptide
D001920	Bradykinin	A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.
